What this shows Toyochem's Innovation Score is 34.8/100 (49th percentile of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Toyochem?

Each dot is one of Toyochem’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Toyochem’s own 9.1 claims/patent is at or below the 17.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Toyochem's grants concentrate

Toyochem Co., Ltd. is a focused PatentsView assignee: 18 CPC subclasses with 53.3% of grants classified under B32B (Layered Products, i.e. Products Built-up OF Strata OF Flat OR Non-flat, e.g. Cellular OR Honeycomb, Form). Peak complete grant year is 2021 (5 grants) versus a trough of 1 in 2018. By volume, Toyochem sits between Tmrw Life Sciences, Inc. and Transseptal Solutions Ltd..

Toyochem's three-year grant acceleration

Toyochem Co., Ltd. shows 5 grants in 2022–2024 against only 7 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
